CONFIG_TOUCHSCREEN_ADS7846: ADS7846/TSC2046/AD7873 and AD(S)7843 based touchscreens

General informations

The Linux kernel configuration item CONFIG_TOUCHSCREEN_ADS7846 has multiple definitions:

ADS 7846 based touchscreens found in drivers/input/touchscreen/Kconfig

The configuration item CONFIG_TOUCHSCREEN_ADS7846:

Help text

Say Y here if you have a touchscreen interface using the ADS7846 controller, and your board-specific initialization code includes that in its table of SPI devices.

If unsure, say N (but it's safe to say "Y").

To compile this driver as a module, choose M here: the module will be called ads7846.

ADS 7846/7843 based touchscreens found in drivers/input/touchscreen/Kconfig

The configuration item CONFIG_TOUCHSCREEN_ADS7846:

Help text

Say Y here if you have a touchscreen interface using the ADS7846 or ADS7843 controller, and your board-specific setup code includes that in its table of SPI devices.

If HWMON is selected, and the driver is told the reference voltage on your board, you will also get hwmon interfaces for the voltage (and on ads7846, temperature) sensors of this chip.

If unsure, say N (but it's safe to say "Y").

To compile this driver as a module, choose M here: the module will be called ads7846.
